Application led May 3, 1899. Serial No. 715,432. (No model.)

To @ZZ whom t m/cty concern:

Be it known that I, ANTONIO IZIDRo GoN- sALVEs, a subject of the King of Portugal, residing at Rio de Janeiro, Brazil, have invented certain new and useful Improvements in Window-Stops and I do hereby declare the following to be a full, clear, and exact description of vthe invention, such as will enable 0thers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. This invention relates to rocking stops for holding open or closed French windows, louver-blinds, and the like, these stops being so arranged that the window, for instance, in moving in the one direction depresses the one part of the stop, which after the window has passed is raised by a counterweight and prevents the window from being moved back unless the stop is depressed by hand.

The object of my invention is to provide a new and improved holder for a window, blind, or the like of the character referred to which is susceptible of being practicably used either at the top or bottom or at one side of the window or blind frame. This object is accomplished in the manner and by the means hereinafter described, and specifically pointed out in the claims, reference being had to the accompanying drawings, in which y Figure 1 is a side view, Fig. 2 is a plan, and Fig. 3 is an end view, of the stop for the lower edge of a French window in its normal condition, the dotted lines in Fig. l showing it depressed for passage of the window. Figs. 4, 5, 6, 7, 8, and 9 are enlarged detail views of the several parts. Fig. 10 is a front view of.' a French window or louVer-blind with a stop for the lower edge, as in Fig. 1, and a modified stop for the upper edge. Fig. 1l is a vertical sectional view of the upper part of the window or blind shown inr Fig. 10. Fig. 12 is a view similar to Fig. 10,V showing the stop xed on the window or blind. Fig. 13 is a vertical sectional view of the upper part of the window shown in Fig. 12.` Fig. 14 is a front view of a blind or window, showing the stops as applied to the window-frame above and below the window, respectively. Figs. 15, 16, and 17 are transverse sectional views taken through the lower end of the windows or blinds shown in Figs. l0, 12, and 141. Fig. 18 is a front View of' a portion of a blind, showing the stop as secured to the frame at one side of the blind; and Fig. 19 is a Vhorizontal sectional view of the same.

As shown in Figs. 1, 2, and 3, on an L-frame a, screwed to the fixed woodwork, is pivoted at b a rocking stop c, which at its one end has a heavy part Tcl, constituting a counterweight, and at its other end has its upper side partly curved on a downward slope e. In the several arrangements shown in the drawings the rocking stop c is in each instance constructed at one end with the sloping face e and at the opposite end with the overbalancing-weight CZ, and this stop is also provided in one end with the curved slotf 7o for the passage of a stop pin or screw f through the flanged frame a into the windowframe, while a pivot pin or screw b passes centrally through said rocking stop and flanged frame into the window-frame. The ends of the curved slotf are adapted to strike the stop pin or screw f', and thereby confine the rocking motions ofthe stop within defined limits. The curved slot]L` and pin or screw j" also enable the rocking stop, weighted at one end, to be practically employed either at the top or bottom or at one side of the window-frame, as will be obvious from the several iigures of the drawings, Where like letters of reference indicate corresponding parts.

The device as a whole is simple and economical, easily applied, and reliable in operation. When the lower edge ot' the window passes over the slope e, it depresses this, making the rocking stop take the position indicated by the dotted lines in Fig. l, and when the window has passed the counterweight d causes the other end of the stop to rise to its former position, preventing the window from being moved back until the part e is depressed.

As shown in Fig. 10, the lower stop is the same as that above described; but the upper stop g has no counterweight, but a flange h, which can be pulled down by a hook on a spring-rod t. Y

As shown in Fig. l2, the upper stop is like that shown in Figs. 1, 2, and 3. The lower stop is like the upper stop in Fig. 10, but provided With a knobj, by which` the light end can be depressed, raising the sloped end.

The side stop shown in Figs. 18 and 19 has 5 its heavy part d a little deeper in order to overbalance the other end when the stop is in a nearly vertical position.

Having now particularly described and ascertained the nature of this invention and in ro what manner the same is to be performed, I

I5 one end, the Weight cl atthe opposite end,

and provided in one end with the curved slot f, the pin 0r screwfpassing through the curved slot and the flanged frame into the window-frame and a pivot-screw I) Dassin@ centrallylhrou gh the stop and the said flanged frame, and screwing into the Window-frame, substantially as described.

2. A blind or Window holder, consisting of the rocking stop c having the sloping face e at one end, the Weight d at the opposite end, and provided in one end with the curved slot f, a fixed pin or screw f passing through the curved slot into the Window-frame, and the pivot-screw bi passing centrally through the rocking stop and screwing into the windowfranne, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my namein presence of two subscribing Witnesses.
